Microscopic cross-section of the pylorus. Under microscopy, the pylorus contains numerous glands, including gastric pits, which constitute about half the depth of the pyloric mucosa. They consist of two or three short closed tubes opening into a common duct or mouth. These tubes are wavy, and are about one-half the length of the duct.
Foveolar cells in the antrum of stomach. A skewed cross-section of the columns gives a false impression of being stratified epithelium. Foveolar cells line the surface of the stomach and the gastric pits. They constitute a simple columnar epithelium, as they form a single layer of cells and are taller than their width. Other mucus-secreting ...
They blend into the surrounding tissue and are fixed in position (for example, the retroperitoneal section of the duodenum usually passes through the transpyloric plane). The retroperitoneal regions include the oral cavity , esophagus , pylorus of the stomach, distal duodenum , ascending colon , descending colon and anal canal .
Colipase is necessary, along with bile salts, to enable lipase function. [citation needed] Intestinal juice also contains hormones, digestive enzymes, mucus, substances to neutralize hydrochloric acid coming from the stomach. Various exopeptidase which further digests polypeptides into amino acids complete the digestion of proteins. [citation ...
Plant anatomy or phytotomy is the general term for the study of the internal structure of plants.Originally, it included plant morphology, the description of the physical form and external structure of plants, but since the mid-20th century, plant anatomy has been considered a separate field referring only to internal plant structure.
The human stomach has receptors responsive to sodium glutamate [38] and this information is passed to the lateral hypothalamus and limbic system in the brain as a palatability signal through the vagus nerve. [39] The stomach can also sense, independently of tongue and oral taste receptors, glucose, [40] carbohydrates, [41] proteins, [41] and ...
Cross section of collenchyma cells Collenchyma (Greek, 'Colla' means gum and 'enchyma' means infusion) is a living tissue of primary body like Parenchyma . Cells are thin-walled but possess thickening of cellulose , water and pectin substances ( pectocellulose ) at the corners where a number of cells join.
A germination rate experiment. Plant physiology is a subdiscipline of botany concerned with the functioning, or physiology, of plants. [1]Plant physiologists study fundamental processes of plants, such as photosynthesis, respiration, plant nutrition, plant hormone functions, tropisms, nastic movements, photoperiodism, photomorphogenesis, circadian rhythms, environmental stress physiology, seed ...
